More details of the drowning of a 26-year-old man last Thursday afternoon in Algoma have been released.  The body of Gustavo Angel Aldama Cuellar, was found in the Ahnapee River near the bridge on County S.   Algoma Police Chief Randy Remiker says officers were dispatched to Perry Street for an apparent hit-and-run.  Later, surveillance video showed that Aldama hit a parked trailer near Perry Street and wandered away from the scene towards his residence before going into the river, according to Remiker.  Aldama had reportedly been drinking earlier in the day at an unknown location.  Police Chief Remiker added that the autopsy found nothing suspicious and a toxicology report is still pending.
